Caring for Lynedoch patients at our Port Dover office
Every dental service for Lynedoch patientsGentle habit support
Most children outgrow sucking habits, but some need a little help.
Sucking on a thumb, finger or soother is a natural way for babies and toddlers to soothe themselves. Many children stop on their own. When the habit continues as permanent teeth begin to arrive, it can affect how teeth and jaws develop, sometimes leading to an open bite, protruding front teeth or a narrow upper jaw. Other habits, such as tongue thrusting or nail biting, can also play a role.
Lynedoch parents with questions about a child’s habit can raise them at a checkup at our Port Dover office. The dentist can look for effects on the teeth, explain whether intervention is needed and suggest supportive ways to help your child stop.
Is it a concern
Not every sucking habit causes problems.
Age and intensity matter
Gentle, occasional sucking in very young children is common and often harmless. Concerns increase when the habit is frequent, vigorous or continues as permanent teeth come in. The dentist will consider your child’s age, how often the habit occurs and whether any changes are visible.
Signs of effects on the teeth
Signs that a habit is affecting development include front teeth that do not meet when biting, upper teeth tipping forward, a narrow palate or changes in speech. A callus or red skin on the thumb may also be noticed. The dentist will explain what they see and whether it is likely to self-correct.
Gentle strategies
Encouragement tends to work better than pressure.
Positive reinforcement
Praise your child when they are not sucking their thumb rather than scolding when they are. Reward charts, small incentives and celebrating milestones can motivate children. Involve your child in the decision to stop, especially if they are old enough to understand why it matters.
Understanding triggers
Notice when the habit happens, such as when tired, bored or anxious. Offering a comfort object, keeping hands busy or adjusting bedtime routines may help. If the habit is linked to stress, address the underlying cause. Ask the dentist for age-appropriate suggestions for your child.
Other habits
Several habits can influence developing teeth.
Soothers and bottles
Prolonged soother use can have effects similar to thumb sucking. Bottles in bed, especially with milk or juice, increase the risk of decay. The dentist can advise on when and how to wean from soothers and bottles in ways that suit your child’s age and temperament.
Tongue thrusting and mouth breathing
Tongue thrusting, where the tongue pushes against the front teeth when swallowing, and habitual mouth breathing can affect jaw and tooth development. These may be linked to allergies, enlarged tonsils or other factors. The dentist may suggest speaking with your physician or another specialist if appropriate.
Further help
Some children benefit from extra support.
Habit appliances
If a habit persists despite encouragement, the dentist may discuss a habit-breaking appliance that makes sucking less satisfying. These are typically considered only for older children who want to stop but find it difficult. The dentist will explain how the appliance works and how long it might be worn.
Orthodontic monitoring
If the habit has already affected the bite, the dentist may recommend monitoring or an orthodontic assessment. Some changes improve once the habit stops, while others may need treatment. Regular checkups help track development and guide the timing of any intervention.
Planning your appointment

Oral habit questions
Have a question about your situation? Our team can help you plan a visit.
At what age should thumb sucking stop?
Many children stop on their own by the preschool years. If it continues as permanent teeth begin to arrive, it may affect development. The dentist can assess whether it is a concern.
Are soothers better than thumbs?
Soothers can be easier to wean from because they can be taken away, but prolonged use can still affect teeth. The dentist can advise on timing and strategies for stopping.
Will my child’s teeth go back to normal?
Some changes improve once the habit stops, especially if it stops early. Others may need orthodontic treatment. Regular checkups help the dentist monitor progress.
Should I use bitter nail polish?
Some families try it as a reminder. It works best alongside encouragement and understanding triggers. Ask the dentist whether it might be helpful for your child.
What is tongue thrusting?
It is when the tongue pushes forward against the teeth during swallowing or speaking. It may affect tooth position. The dentist can explain whether it needs attention.
